Connect with blockchain directly from your phone

[Serpensfinance]

Hello, my name is Rafael, I'm a c++ programmer.

It is with great pleasure that I share a project that we have been working on for months that consists of connecting the user to the blockchain without having to have a server hosted on their machine.

We know that this was a current need, so yes it is a wallet where you generate your wallet or import it with one click and you can receive and send transactions with the lowest rates on the market.

For now we only support Dogecoin, but we are already working to put bitcoin.

First of all, maybe I'm mistaking, but you should check what API you use in your app, since Google tells it's not compatible with my Android 11. I see you ask for a version for wearables?!

Second: is this a SPV wallet? Does it work with the actual blockchain and official wallet RPC, hosted by you (I would doubt that) or is it working with a custom server/database built on top of the official wallet/blockchain, like Electrum does?
Or is it something else (eg. custodial)?

This wallet is not open-source I can't find any links that you have a team or a Github page with your team so I and most of the people here do not trust any wallet without open-source code.

How can I trust you?
Based on what I see from the images in Google playstore it's totally a wallet with no APIs and JSON RPC commands so how we can connect to the blockchain if it was just created for sending and receiving coins?

You must edit your title and thread that your project is a wallet and it is still underdeveloped.

The interesting thing about being a wallet without its own system is that at any time we can end activities in a country, and you will still have your coins through the private key

We are directly connected to the blockchain without bridges, for those who are afraid I understand because it is something new, but the minimum for sending is 0.50 doge if you want to test our system you will need $.29

I think you're missing the point of the question. It is not about owning a private key or not, but how can the user make sure nobody else own the private key, or they are not using some address generated by others. If you have no reputation then going open source should be a good idea.

So you claim to be non-custodial. Is this correct?

This doesn't make any sense to me... You either DOWNLOAD and verify the complete blockchain (which is close to impossible on a cellphone due to it's size and the amount of processing power you need to parse all blocks) OR you connect to a node... which one are you? Do you download all blocks on the phone or do you use a server and are you promoting an SPV wallet?

How are you going to fit the Bitcoin Blockchain onto a mobile phone's limited memory? (Pruned version?) ..... because I know there are a huge demand for this to be developed for 3rd world countries with older phones.

Have you calculated the bandwidth it will need to update the Blockchain for both Bitcoin and other Alt coins that will be running on the phone? (Mobile data are very expensive in my country)

Yes, clearly we are a server, when I say "no bridges" I mean other corporations like electrum or web3

I'm not going to go into semantics, but electrum and web3 aren't centralised corporations, and your server IS a centralised corporation...
I don't think web3 is worth discussing, but electrum is relevant in this case. Electrum nodes are ran by private individuals. Electrum is completely open source and anybody who knows python can read the sourcecode to make sure their master private key, derived keys, seed phrase,... are never ever sent to a node. Next to this, your local electrum client fetches block headers from 8 different (decentral) nodes so the node it gets it's tx data from is very unlikely to cheat...

Now, i'm trying to be constructive here, and i'm trying not to be mean... You have written a wallet, but going on the way you answer the questions we pose, i can't shake the feeling you might not have the technical background necessary to write a wallet... I mean, you make a lot of confusing (and sometimes wrong) statements and you seem to be having troubles answering our questions in a clear manner....

I'd still give you the benefit of the doubt so i won't post what my gut tells me, but i would never use a wallet that:

• first claims to have "no bridges" but then suddenly has to admit they use a centralised server
• whilst in the meantime calling electrum a "corporation" having "bridges"
• and at the same time not being able to conclusively tell us if it's an SPV wallet or not
• and having a closed source binary

If you want to build trust in this community... Get your house on order...
Give us all the technical details, preferably let somebody trusted in the community read the sourcecode... Really...

I'll do it for you.

The Bitcoin community is known for seeking transparency, open-sourceness and the like, so it's highly suspicious to appear out of nowhere, with no additional information of who you are, with no provable work in a repository, and publish a closed-source wallet software, just like that. With this background, I consider you rather potentially harmful and untrustworthy until proven otherwise.

We can neither verify your credibility, neither can we trust you. You're a big no for this place.

The first answer you gave me was somehow implying your wallet is connecting directly to the blockchain.
After far too many questions that whould have been needed when discussing with somebody involved in the project and knowing what are bitcoin wallets about, you come with

Yes, clearly we are a server, when I say "no bridges" I mean other corporations like electrum or web3

You still didn't say clearly what's this wallet about. You are just going around the questions. And that's suspicious, no matter what you will add to this.
I won't even tell about the closed source setup, that's already covered.

So, sorry, but I have to agree with BlackHatCoiner here:

We can neither verify your credibility, neither can we trust you. You're a big no for this place.
